Positive feedback loops, action potential

Antioxidant effects. Superoxide (02 ) is a free radical which contributes to oxidative stress, a process which causes significant damage to the molecular structure of cells. NO induces the synthesis of endothelial cell superoxide dismutase (ecSOD) the enzyme which forms hydrogen peroxide H2O2 from 02 A positive feedback loop is set up as H202 induces eNOS which produces more NO and so on. This is a protective action as superoxide which is potentially damaging to cells is buffered by NO ... [Pg.135]
